Should I Have Been Eating Gluten Prior To These Tests?

My gastroenterologist ordered some blood tests for celiac; my results are below. His nurse told me based on the results that I don't have celiac and am not at risk for developing it. However, I had been on a gluten-free diet for months prior to the tests. (Occasionally some gluten slips in, but I am pretty careful.) Does that render the below tests invalid?

Your results are negative for antibodies related to celiac disease, but if you have not been eating gluten then there will not be antibodies--at least not enough to register on the test. I was retested a few years ago, and everything was normal. Does that mean that I no longer have celiac disease? NO! It means that I have been very successful in following the gluten-free diet, and there is not any gluten in my food to trigger the autoimmune response. :)

You need to be eating the equivelant of 2 to 3 slices of bread a day for about 2 months or longer for any chance of a positive test.

It looks like you have one or two HLA DQ 2 markers and that means that you are predisposed to developing Celiac Disease. I can't tell exactly what test they did - they call it a molecular test which may not mean they actually determined which DQ allele(s) you inherited so we can't tell whether you are high risk or low risk. Call the lab which did the test and ask them to tell you what it means and if you would get more information if you had the DNA marker test.

      Persistent isolated high DGP-IGG in child despite gluten-free diet

      Thanks very much for taking the time to write this. I have been pretty worried so appreciate reading any advice. Yes, the endoscopy will include a biopsy, and we have hopefully found a good pediatric gastro to guide us through it all. Will also run the HLA typing - I have the swabs ready to go.

      Persistent isolated high DGP-IGG in child despite gluten-free diet

      Welcome to the celiac.com community, @melthebell! I certainly would have a biopsy repeated as it has been 5 years since the first one. You mentioned he was scheduled for an endoscopy but make sure a biopsy is also done. It's possible he, like you are, is a "silent" celiac where the damage to the intestinal mucosa happens very slowly and can take years...

      Persistent isolated high DGP-IGG in child despite gluten-free diet

      Hello community; it's nice to have found you. I am a 42 year old biopsy confirmed celiac. I have had it since I was 18. Well managed on a gluten free diet. No idea if I have the gene (presume I do) as never tested. Diagnosed as was anaemic and had a high celiac market (can't recall which), and a positive biopsy. Asymptomatic. Given this, I regularly...

      Why Celiac Diagnosis Still Takes Years—and How to Change That

      @par18, I don't totally disagree with what you say in theory. But like many things in life, one size doesn't fit all. While a formal diagnosis of celiac disease or NCGS is certainly not essential since, in the big picture of things, eliminating gluten is the antidote to either, there are some other considerations that give importance to seeking a formal diagnosis...

      What would you do - neighbor brought gluten-free pizza from Papa Murphy's

      Domino's and Mountain Mike also has glutenfree pizza.However the issue is the cross contamination. Not worth a few minutes of yum yums i n the taste buds with a painful explosion later.

      Welcome to the celiac.com community, @melthebell! I certainly would have a biopsy repeated as it has been 5 years since the first one. You mentioned he was scheduled for an endoscopy but make sure a biopsy is also done. It's possible he, like you are, is a "silent" celiac where the damage to the intestinal mucosa happens very slowly and can take years to manifest to the point of being detectable and where symptoms are minimal or absent. At 10 years old, his immune system may not be mature enough het to trigger the usual IGA responses that the IGA celiac tests are designed to detect.  I would also have genetic testing done to confirm that he has or doesn't have the potential to develop celiac disease. The genetic profile can also offer insight into the type of celiac disease a person will develop if they ever convert from latent to active. Take a look at table 2 under the section "Types of Celiac Disease" in the article found in this link: https://pmc.ncbi.nlm.nih.gov/articles/PMC9980758/  Genetic testing is available from 3rd party labs. I think you just have to send in a cheek swab sample.

      Hello community; it's nice to have found you. I am a 42 year old biopsy confirmed celiac. I have had it since I was 18. Well managed on a gluten free diet. No idea if I have the gene (presume I do) as never tested. Diagnosed as was anaemic and had a high celiac market (can't recall which), and a positive biopsy. Asymptomatic. Given this, I regularly test my two children. My eldest is the child in question. First tested at age 5 due to slight anaemia. Everything negative except for a slightly high DGP IGG (slightly elevated at 25). Not IGA deficient. Did a biopsy with a pediatric gastro, was negative. Next test at age 8. Everything once again negative, high DGP IGG at 116 U/ml this time. Living in a country now with no celiac knowledge so decided to whack him on a gluten-free diet and see how he goes. Next test at age 9 after a year on gluten-free diet. Everything once again negative, high DGP IGG at 174 U/ml this time! On a gluten-free diet. Final test was a week ago at age 10, on continued gluten-free diet. Once again a positive DGP IGG, this time over 250 U/ml. On a gluten-free diet. what the heck is going on with my kid? We have seen a pediatric gastro via telehealth, who was equally puzzled and suggested doing a gluten challenge and an endoscopy, which we have schedule for end of April. Kid is otherwise fine. Energetic and growing well. No significant gastrointestinal symptoms. Has anyone encountered something like this before?

      Reverse Osmosis (RO) Water

      By Scott Adams · Posted

      I don't recall seeing "many people here recommending RO water," but reverse osmosis (RO) water is water that has been purified by forcing it through a very fine membrane that removes dissolved salts, heavy metals, fluoride, nitrates, PFAS, and many other contaminants. It is one of the most thorough household filtration methods available and can be especially beneficial in areas with well water or known contamination concerns. While RO systems also remove beneficial minerals like calcium and magnesium and may produce slightly “flat”-tasting water, most dietary minerals come from food rather than drinking water, so this is not usually a health concern for most people. Overall, RO water is very clean and safe to drink, and it can be a smart option where water quality is questionable, though it may not be necessary in areas with well-tested municipal water.
